Daft little project drawing rubber band lines between moving objects. 1 moves left & right slowly, 2 draws a circle and 3 follows the mouse pointer. Press space bar to toggle whether lines are cleared or not so you can make patterns.
Idea for drawing lines this way from the awesome 3D project here: https://scratch.mit.edu/projects/129124/#editor Circle algorithm from https://www.mathopenref.com/coordcirclealgorithm.html
